Starting Cassandra as a service

Start the Cassandra Java server process for packaged installations.

Start the Apache Cassandra™ Java server process for packaged installations.

Start-up scripts are provided in the /etc/init.d directory. The service runs as the cassandra user.

Procedure

You must have root or sudo permissions to start Cassandra as a service.

On initial start-up, each node must be started one at a time, starting with your seed nodes:

sudo service cassandra start #Starts Cassandra

If Cassandra fails to start:

Reloading systemd:                                         [  OK  ]
Starting cassandra (via systemctl):  Job for cassandra.service failed because a configured resource limit was exceeded. 
See "systemctl status cassandra.service" and "journalctl -xe" for details.
                                                           [FAILED]

The Cassandra service is not enabled on newer Linux systems, which use systemd. To verify use:

sudo systemctl is-enabled cassandra.service

cassandra.service is not a native service, redirecting to /sbin/chkconfig.
Executing /sbin/chkconfig cassandra --level=5disabled

To start Cassandra:

Enable the service:

sudo systemctl enable cassandra.service

cassandra.service is not a native service, redirecting to /sbin/chkconfig.
Executing /sbin/chkconfig cassandra on

Start Cassandra:
```
sudo service cassandra start
```

To check the status of Cassandra:

nodetool status

The status column in the output should report UN which stands for Up/Normal.
